I believe they are 7-11. I had a few charges from Sei show up on my statement. I did some thinking and realized they were from 7-11 purchase. So, my best guess is it maybe stands for Seven Eleven Inc. Maybe?

Agreed! The charges are indeed from 7-11. In my instances, they are from gasoline debit transactions typically forgotten about.

this is not fair I will never shop here again! In fact I want my money back. They have charged me this fee at least 5 times. And you are not told about it all. In fact, I thick I will sue them for fraud.

This has to be correct. Thanks for the help. I hat the same charge on my card and realized after reading this article and comments that I went to 7-Eleven and bought two monsters for $4.29 plus tax brought it to $4.67. That is exactly what showed up on my card under SEI. Hope this helps others as well.

Today I received a charge on my card for $100 from SEI 29314. I have never been to the gas station that this charge came from, nor do I have any idea how they came across my card information to even charge me. I believe that I am a victim of fraud.

Had 3 charges from this 7-11 and I NEVER frequent this location. Had three other 7-11 gas charges from other locations I have never been to on same (co. gas) visa card in last month's statement. This makes me think someone is using a card reading scanner device at these stores gas pumps. At certain times in the day clerks ars so busy, at these type of convenience stores tin particular, that the thief doesn't get noticed. We're usually in a rush to get somewhere ourselves and do not take the precaution of checking the pump card readers the way we should, either, and the thieves probably found a device that works exceptionally well in these location's type pump card reader's as well. I got scammed, anyway!

Went to get gas at a 7-Eleven outside Castle Rock… pumped and random charges went thru. Immediately. Avoid 7-11’s in the South Denver metro… pay inside
